Very nice. I don’t author parts, so I won’t be trying it out. However, I looked at your tutorial, and I have two suggestions:

Add “Un-Project”, where it takes a projected shape and flattens it automatically on an axis specified by the user (X, Y, or Z).
Automatically split pattern polygons so that they don’t cross any polygon boundaries of the template part. Use the un-projected geometry that you generated in the above as the “pre-projected” template, and do the splitting while the pattern is still flat.

The first feature above is probably pretty trivial. The second one would likely be a lot more work, but would make the tool a whole lot more powerful.

(...) For unproject MLCad does the job. Symply select everything and set the appropriate matrix row at 0. This is perfect for triangle, quads... If you have primitives you have to later automatically fix the "all zero matrix row" using LDDP. The (...) (16 years ago, 8-May-08, to lugnet.cad.dev, lugnet.vikings, lugnet.castle, FTX)
